This invention relates to reservoir markinginstruments, and has for its object to provide an improved article of this kind which is simple in construction and reliable in operation, and is 5 particularly suitable for writing or marking ters, announcements, display cards, and the e. A marking instrument, according to my invention comprises a body or barrel whereto is iltted l0 a section having a through passage; a collapsible ink reservoir or sac disposed within said body or barrel and attached to said section and with which an end of said section-passage communicates; a nozzle, or 'the like, secured to the section; and a felt or other absorbent marking tip or equivalent pad carried by said nozzle, or the like, and to the inner end of which tip or pad the other end of said section-passage opens; the arrangement and disposition of the parts being auch that when said reservoir or sac is compressed by means of a lever and presser bar, or other sac-actuating mechanism, a charge of ink is ejected to saturate said tip or pad.

I will further describe my invention with the aid of the accompanying sheet of explanatory drawings which illustrate. by way of example only, one mode of carrying the same into effect.

In said drawingz- Fig. 1 is a longitudinal sectional elevation of a marking-instrument constructed under this invention.

Fig. 2 isan elevation of the end section with collapsible reservoir attached, disconnected from the body or barrel of the instrument.

Figs. 3 and 4 are detail elevations, taken at right angles to each other, of the nozzle which carries a felt marking tip or pad.

In the views like characters of reference denote like or equivalent parts wherever they occur.

Referring to the drawing, a generally designates the tubular body or barrel of the markinginstrument which is made from casein, vulcanite, or other suitable material. Within the front of barrel a there is iltted a shouldered section b of similar material, a circular intermediate portion whereof being longitudinally serrated or scored s at b1 so that it will bite into and make frictional engagement with the inner wall or bore a1 of barrel d: such wall or bore portion may also be correspondingly serrated or scored to co-operate in such engagement.

(ci. izo-4s) An enlarged portion of a tubular extension b2 of the section is screw-threaded at b3 for engagement with a correspondingly internally screwed end of a metal tube or nozzle c, the` opposite (outer) end whereof is iiattened at c1 tosecurely 5 hold or carry a marking tip or pad of felt or other suitable or equivalent material d, the inner end whereof disposed within said tube or nozzle c touches or contacts with the mouth of tubular extension lz of the section, and which mouth 10 constitutes the opening at this end of a passage b4 formed longitudinally through the section. The other end o! the through-passage b* communicates with a-collapsible ink reservoir or sac e attached to a reduced end portion b of section b 15 in similar manner to ink sacs of Areservoir pens;

in the example illustrated the sacl e' is actuated by presser bar f and lever y mechanism, also of the type as customary to sac self-filling reservoirk pens. 20

The front end of the barrel a is screw-threaded for engagement with an end caprvor cover h.

Ink ejected by actuation of the lever g to compress sacV e saturates the absorbent marking tip or pad d ready for writing or marking by they end thereof protruding from knozzle c: in this manner the supply'of ink to the tip can be regulated as required. e

It will be obvious that any other sac-actuating means may be employed without departure from the invention. v y What I claim asmy invention and desire to secure by Letters Patent isz-,-

A marking instrument comprising a barrel carrying sac-actuatingmechanism and whereto 35iv is fitted a section having a through passage; a tubular member forming an outward extension of said section; a collapsible ink sac'disposed, within said barreland attached to said section y and with which said section-passageand tubulary 4 I,

extension communicate; a nozzle encompassing the tubular extensin and removably iltted yto the section; and an absorbent marking tip ilxedly secured to said nome and to the inner end of which tip the adjacent endof said tubular extension makes contact: the arrangement and disposition of the parts being such thatwhen said sac is compressed by means of 'the actuating mechanism, a charge of ink is ejected to saturate said absorbent tip. i 5o BIEGFRIED LUNZER.
